I kinda want to ask this,

the last few months (I am not sure for how long it have been but lets just say 2 monts)
I feel my T have started to show for real.
I am finally started to get some actual facial hair after being around one and a half year on T, voice voice still getting deeper even when its pretty deep now, and I am getting more sweeety(which I dont like XI)
-
But I feel something wierd, like I somethimes I get heartbeats like I get very emotional, kinda restless, upset, confussed, all kind of felling for no reason, and then it stops a time afterward.
I dont know if this is like normal fellings who just happent and I notice, or moodswings. one of my mtf friends said its a normal moodswing for teenegers and I shouldnt worry too much about it, but its feels pretty bad and I get all annoyed, doubtfull, depressed, confussed, restless and all those kind of feeling with mix of worryes why I am felling this or why my heart seams to beat so fast out of sudden, when I get it
has any of you got this?
is it normal or do I need to be concerned?
